SPECIFICATION orming, part of Letters Patent No. 382,61 6,'diat,ed May 8, 1888*.

Application tiled March Q5, i887. Serial No. 232,337. (No model.)

To all whom it may concern:

Be it known that I, WALTER MARKLE, of Ton ganoxie, in-the countyof Leavenworth and State of Kansas, have invented a new and useful Improvement in-I-Ieating-Drums, of which the following is a specification. Y

My invention is a heating-drum intended especially for heating upper apartments and thereby utilizing the waste heat from below, but which, as will'lbe manifest, may be used in any location in which the heat may be con ducted to it, and will serve to increase the heating or radiating surface.

The invention consists lin certain improvements whereby air may be drawn from the heated room without admitting smoke or gas thereto, and in certain other features of consruction and combinations 'of` parts, as will be described, and pointed'out in the claims.

In the drawings, Figure 1 is a side View; Fig. 2, a verticalsection; Fig. 3, a transverse section of my improved drum. Fig. 4 is a transverse section of the Ventilating-chamber, and Fig. 5 shows another form of stand.

My drum comprises lower and upper cones or chambers,-which are so termed because of their shape, which is preferred, but obviously the shape might be varied without departing from my inventiona main central iiue, a number of supplemental or heating. tubes located around said central flue, headplates connecting the tubes and cones and the 4Ventilating-chambers and dampers, together with the stand, all of which will'be described.

The cones A and B are preferably cast, as are also the headplates C D and the ventilating-chamber plates E and F. The lower cone, A, is suitably connected at its lower end with the smoke or heat pipe, and rests near its upper end in the stand G, which has legs g, fit` ting between lugs a', formed'on cone A. This stand forms a simple and convenient support for the drum, and by the aid of lugs a serves to secure it steadily in position. The legs g curve outward beyond the point of connection with the drum and supporta connecting-ring, G', which forms a convenient foot-rest while warming the feet.

The central iiue, H, and supplemental flues I extend between and connect the lower and upper head-platea() D, ,such iues opening at their ends into the cones, as shown in Fig. 2.

Within the'main flue, below its upper end, I provide a damper, h, having a suitable out wardly-extended handle by which it may be opened or closed, The nppervcone, B, has its lower end fitted to the iiange d of the upper headplate, D, while its upper end is formed to fit snugly the; iiange j, depending from the head-plate F of the Ventilating-'chamber K. The topplate, E, of such chamber has an upwardly-projected collar, Z, formed 'to receive the uptake-pipe M. e This chamber K has in its outer wall anopening, k, and a valve, N, is arranged to close such opening. This valve is preferably a cylinder, as sho w n, fitted around the Ventilating-chamber, and having a handle by which it may be turned,'an'd being provided with an opening, n, whichmay be brought intoA 4the protector-plate7 O, which is fitted and preferably held in grooves o, formed in plates E F. The ends of this plate extend considerably beyond the ends of the opening k, for the reason more fully described hereinafter.

Having described the construction, I shall now proceed to describe its operation and advantages. If little or no heat is desired in the rooIn,the damper h may opened,when the heat will pass directly up the main central flue and but little will circulate' through the supplemental tubes I; but by w-holly or partially closing damper h the heat may be caused tocirculate to any desired degree th rough tubes I. When the damper h is closed, the spaces within the iiue H above such damper form a Space into which the 'deposited soot and the like are likely to fall, as when valve h is closed there is no upward draft through such space to impede the deposition of the soot, &c., therein, and vsuch deposit Ymay be thrown thence back into the fire by simply dumping the damper, thus preventing the burning out of the iues and the consequent danger of re to the house. .The Ventilating-chamber serves to carry oii' the foul air from the'room, and by means of the protector-plate the escape of smoke or gas is avoided, as the indowing foul air forming an inward circulation around the ends of said plate serves to prevent the exit of smoke and gas. Thejoints between the castings are tight, and act to prevent the escape of smoke, soot, gas, and the like at'such points. The form of stand shown in Fig. l may be preferred when the part A is cast,while that shown in Fig. 5 may be preferred when such part is formed of sheet-iron or other metal.

It will be understood that the Ventilatingchamber, in addition to its functions before described, may serve to modify the force of the draft through the drum, and thus in a certain degree operate to increase or diminish the heating capacity of said drum, as may be desired. Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s.-

1. The combination of the heating chamber or drum and the Ventilating-chamber K, having an air-inlet opening,k,and a protectorplate located within said chamber K opposite its inlet-opening, a passage or passages being provided between the protector-plate and the wall of the Ventilating-chamber and laterally to the opening lr, for the passage of the air entering through opening 7c into the ventilatingchamber, substantiall y as and for the purposes specified.

2. The combination of the heating chamber.

or drum and a Ventilating-chamber, K, having plate, O, combined with a valve whereby to close said opening at will, the plate O being extended past the opposite sides of opening k, passages for the inlet of foul airbeing provided laterally to said opening k, as and for the purposes specified.

3. The combination of the stand G, having legs g and ring G', the drum fitted in said stand,and the lugs aa,projected laterally from said drum and on opposite sides of the legs g, whereby to prevent any turning of the drum in the stand, substantially as and for the purposes specified.

4. The combination of the chamber B, the Ventilating-chamber K, mounted on chamber B, and having an opening, k, the protectorplate O, located within chamber K and having its ends extended to opposite sides of and past the opening k and separated at its ends from the walls of chamber K, forming openings for the passage of the air entering through opening 7c, the lower chamber, A, and tubes connecting said chambers A B, substantially as and for the purposes specified.

5. The combination of the heating chamber or drum, the chamber K, having opening k, and having end plates provided on their inner sides with grooves o 0, the connection uniting said end plates, and the protector-plates O,held in said grooves, all being arranged substantially as and for the purposes specified.

VALTER MARKLE.
